IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent No. 25,006, dated August 9, 1859.

To all whom it may concern.-

Be it known that I, PARLEY F. FREELAND, of Newark, in the county of Kendall and State of Illinois, have invented a new and improved Cultivator; and I do hereby declare that the following is afull, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1 is a side view of my invention. Fig. 2 is a front View of the same. Fig. 3 is a plan or top view of the same. Fig. 4 is a secti n of one of the shares of the same, taken in the line .10 a, Fig. 2.

Similar letters of reference indicate corresponding parts in the several figures.

The object of this invention is to obtain a cultivator which may be made to answer equally well for eradicating weeds and pulverizing the soil, and for billing or earthing up plantsin short, an implement that may be used for general work in the cultivation of what are generally termed hoed crops, or such as are grown in bills or drills.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents what may be termed a tongue or draft-pole, to the back end of which a segment or curved bar, B, is permanently attached.

O O are handles, which are attached to the tongue and bar, as shown clearly in Fig. 3.

To the back part of the tongue A a doubletree, D, is attached, and to each side of the tongue A a beam, E, is attached by a bolt, a, the bolt passing loosely through the front ends of the beams, so as to admit of a lateral adjustment of the back ends, which are securedv to the curved bar B by means of thumb-nuts t b, which are fitted on screw-rods c c, that are attached to the back ends of the beams E E and pass upward through curved slots d in the ends or outer parts of the bar B.

To the back part of each beam E a pendent bar, d, is attached. These bars d are braced from the bolt a by rods 0, and to the lower end of each pendent bar (1 a share, F, is attached. These shares F are constructed of two parts, f g. The parts f are attached permanently to the pendents d but the parts 9 are attached to the upper and inner parts of the parts f by bolts h, which pass through the parts fand through bars t, attached to the backs of the parts g. (See Figs. 1 and 4;.) The shares F are placed in oblique positions,their back ends being nearer together than their front ends, as shown in Figs. 2 and 3, and the shares areiir clined from a vertical position, as shown clearly in Figs. 1 and 4. The two partsfg of the shares are metal plates, and both parts, when connected together, form a plane surface, the parts 9 fitting in and filling up a curved recess in the inner and upper parts of the shares.

The operation is as follows: When the earth is to be merely pulverized and weeds eradicated the parts 9 of the shares are detached and the earth passes over them, the partsfof the shares merely eradicating the weeds and pulverizing the soil. When plants are to be earthed up or hilled the parts 9 are attached,

and the shares F then throw the earth up to the plants which are between the shares F. By adj usting the shares F nearer to or farther from each other, which is done by relaxing the nuts b, shiftingthe beams E, and securing them at the desired point by screwing down the nuts I), more or less earth may be thrown toward the plants, as may be requird.

It is designed to havethe tongue A and bar B suflieiently elevated by means of the pendent bars (1 that the ton gue-bar will clear the tops of the plants.

By this invention a very compact and efficient implement is obtained for general use one capable of operating efliciently in all work required to be performed in the cultivation of crops that are grown in hills and drills.

I am aware that expanding eultivators have been previously used and arranged in various ways, and I do not claim broadly such device irrespective of the construction and arrangement herein shown and described; but,

Having thus described my invention, what I do claim as new, and desire to secure by Letters Patent, is-

The arrangement of the tongue A, curved or segment bar 13, beams E E, with screw-rods c, and pendants d, and shares F attached, substantially as and for the purpose set forth.

PARLEY F. FREELAND.
